This example demonstrates how to represent unequal fractions on a number line. It involves core math concepts like fraction comparison, ordering, and number line representation. GeoGebra commands used include Polygon, Sequence, Point, Segment, Circle, and SpeechBubbleRight for construction. Suitable for 5th-6th grade students to practice fraction comparison and number line plotting skills.

GeoGebra Commands & Parameters

  1. Polygon((1, Höhe - 0.15), (13.5, Höhe - 0.15), (13.5, Höhe + 0.15), (1, Höhe + 0.15)) → V1, h, i, j, k
  2. Sequence(SAnfang + (i * (0.5, 0)), i, 6, 20) → listSPos05
  3. Point(listSPos05) → S
  4. Segment((4, Höhe), (11, Höhe)) → f
  5. Polygon(Sp_1, Sp_2, Sp_3, Sp_4, Sp_5, Sp_6, Sp_7) → Sprechblase, sp_1, sp_2, sp_3, sp_4, sp_5, sp_6, sp_7
  6. Segment(SAnfang, S) → s
  7. Segment((1, Höhe), (längeZS, Höhe)) → ZSNeu
  8. Sequence(Segment[(i, Höhe - 0.1), (i, Höhe + 0.1)], i, 1, längeZS, 0.5) → Unterteilung4
  9. Segment((13, Höhe), (13.5, Höhe)) → sEnde
  10. Circle((If[correct4, 2.5, If[correct8, 4]], 5), 0.25) → KA1B1
  11. Circle((If[correct4, 3.5, If[correct8, 6]], 5), 0.25) → KA1B2
  12. Circle((If[correct4, 6.5, If[correct8, 12]], 5), 0.25) → KA1B3
  13. Circle((If[correct4, 4, If[correct8, 7]], 5), 0.25) → KA2B1
  14. Circle((If[correct4, 3, If[correct8, 5]], 5), 0.25) → KA2B2
  15. Circle((If[correct4, 3.5, If[correct8, 6]], 5), 0.25) → KA2B3
  16. Segment((1, Höhe), (0.2, Höhe)) → g
  17. Sequence(Segment[(i, Höhe - 0.1), (i, Höhe + 0.1)], i, 1, längeZS + 0.5) → Unterteilung8
  18. SpeechBubbleRight(A, 7, 1) → Vieleck1
  19. SpeechBubbleRight(B, 9.7, 1.7) → Vieleck2

AI Drawing Prompt Reference

Draw a number line from 1 to 13.5, marking every 0.5 with a line. Label the fractions 1/2, 2/3, 3/4, 4/5, 5/6, and 6/7 on the number line and mark these points with circles. Draw two vertical lines at the ends of the number line. Place two speech bubbles at positions 4 and 7, labeling them '1/2' and '2/3' respectively.
